@Ali:

I think that there is a saying: Be careful what you wish for because you might receive it!

IF you have a needed skill, then you would probably like the United States. There are many vacant jobs that require important skills.

IF you are poorly educated, however, it is very difficult to find a job that will pay enough money to live in a big city.

I notice that you come from Iran.  As you know, many Iranians live in the States. Maybe some of them will help you find a job. On the other hand, most of them came here in the 1980's (you know the reason). Maybe many of them would not be too happy to help you. (You know what I mean)

Also, remember that although almost everyone in Iran is Iranian, the United States is very "diverse."

That is, there are many races, religions, etc. There is much competition among those groups for jobs, etc. Furthermore, there are many dangerous neighborhoods in which poor people are forced to live. If you do not have enough money to live in a nice neighborhood in a nice city, then life could be very dangerous and unpleasant.

I do think, however, that you -- as a young person -- would like the fact that there are some freedoms here that do not currently  exist in your country.

Good luck! It may be the most important decision of your life.

Why do you think so? Because Hilarie said you have the rights to be an idiot in US? US conducts the most strict laws in the world, do you know why? Too many bold and smart people with guns and lawyers....which makes the percentage of people going to jail highest in the world!!!! Why do you think life can be easier between such people?

Have you met anyone who'd left their home country for America? I don't know what kind of situation you're in, but living in a foreign country certainly has its pros and cons. I lived there for school, and my life wasn't easier but rewarding. 

In my opinion, living aimlessly without a purpose, or a goal in a foreign country can be really empty and possibly a waste of time. Many immigrants move there for opportunities, which means they have some goals they hope to achieve. It could be a better standard of living, political freedom, job, family etc. They would have what it takes to put up with the cons of leaving their home countries in order to work hard to get what they want. 

I have friends there, so it will be fun to visit the country. However my life won't be infinately better just to be in the U.S., just like being in any other country for that matter. It all depends on what I could get out of living there.

I don't know if I would like to live there but I would definitely love to visit! :)

I already live in America,I´m Uruguayan,I live in South America. I don´t want to live in the United States, I think my country is the best placa for me and my family. I can´t complain,may be there are better countries,but this is my place.
